XT 582 Maintenance Manual
Issue 1.0

Check Clearance
The dimension measured will have some variability, but should be in the range of 20 to 15mm.
NOTE 1
The dimension should be measured with the wing off, and no pilot in the seat, as this will alter the
dimension.
NOTE 2
If the two tubes are closer than the recommended distance or interfere with each other, this indicates
significant deformation of the trike base tube, and that the trike has been subjected to significant
abnormal loads. The Base Tube should be replaced, and this necessitates a thorough checking of the
rest of the aircraft.
Check Alignment
The alignment of the mast brace with the top of the mast can be checked by ensuring that the two
tubes slide freely over each other.
NOTE
The sliding should be measured with the wing off, and no pilot in the seat, as this will change the
alignment of the tubes.
Attachment Points
Check attachment points for the wing to the base, including the main hang bolt, wheel axles and
bearings. The wing should also necessarily be checked after any heavy landing because the forces are
transmitted through to the wing structure.
Check the main structure including the base tube, Landing gear attachment points and engine mount.
Check all other components attached to the base are in place and properly secured.
Seat Frame
If the airframe has experienced unusual loads then the seat frame should be checked thoroughly. The
weight of the pilot during impacts may deform the seat frame.
5.50.20 Inspection after heavy turbulence.
Check all components attached to the base are in place and properly secured, any other items that may
have shifted due to in flight movement should also be checked on a regular basis.
Turbulence is more likely to structurally effect the wing of the aircraft rather than the base. The Wing
Maintenance manual should be consulted for instructions that pertain to the wing.
